No Evidence for Chemical Abundance Variations in the Intermediate-age Cluster NGC 1783
Hao Zhang, Richard de Grijs, Chengyuan Li +1
We have analyzed multi-passband photometric observations, obtained with the {\it Hubble Space Telescope}, of the massive (), intermediate-age (1.8 Gyr-old)…
The Near-infrared Optimal Distances Method Applied to Galactic Classical Cepheids Tightly Constrains Mid-infrared Period--Luminosity Relations
Shu Wang, Xiaodian Chen, Richard de Grijs +1
Classical Cepheids are well-known and widely used distance indicators. As distance and extinction are usually degenerate, it is important to develop suitable methods to robustly an…
The NGC 7742 star cluster luminosity function: A population analysis revisited
Richard de Grijs, Chao Ma
We re-examine the properties of the star cluster population in the circumnuclear starburst ring in the face-on spiral galaxy NGC 7742, whose young cluster mass function has been re…
Not-so-simple stellar populations in nearby, resolved massive star clusters
Richard de Grijs, Chengyuan Li
Around the turn of the last century, star clusters of all kinds were considered "simple" stellar populations. Over the past decade, this situation has changed dramatically. At the…
An internally consistent distance framework in the Local Group
Richard de Grijs, Giuseppe Bono
Accurate and precise astronomical distance determinations are crucial for derivations of, among others, the masses and luminosities of a large variety of distant objects. Astronomi…
The VMC Survey XXVII. Young Stellar Structures in the LMCs Bar Star-Forming Complex
Ning-Chen Sun, Richard de Grijs, Smitha Subramanian +11
Star formation is a hierarchical process, forming young stellar structures of star clusters, associations, and complexes over a wide scale range. The star-forming complex in the ba…
The VMC survey - XXVI. Structure of the Small Magellanic Cloud from RR Lyrae stars
T. Muraveva, S. Subramanian, G. Clementini +10
We present results from the analysis of 2997 fundamental mode RR Lyrae variables located in the Small Magellanic Cloud (SMC). For these objects near-infrared time-series photometry…
The Optical -- Mid-infrared Extinction Law of the l=165 Sightline in the Galactic Plane: Diversity of Extinction Law in the Diffuse Interstellar Medium
Shu Wang, Biwei Jiang, He Zhao +2
Understanding the effects of dust extinction is important to properly interpret observations. The optical total-to-selective extinction ratio, Rv = Av/E(B-V), is widely used to des…
Clustering of Local Group distances: publication bias or correlated measurements? V. Galactic rotation constants
Richard de Grijs, Giuseppe Bono
As part of on an extensive data mining effort, we have compiled a database of 162 Galactic rotation speed measurements at (the solar Galactocentric distance), . Publishe…
Mira Variable Stars From LAMOST DR4 Data: Emission Features, Temperature Types, and Candidate Selection
Yuhan Yao, Chao Liu, Licai Deng +2
Based on an extensive spectral study of a photometrically confirmed sample of Mira variables, we find a relationship between relative Balmer emission-line strength and spectral tem…
The VMC Survey. XXV. The 3D structure of the Small Magellanic Cloud from Classical Cepheids
Vincenzo Ripepi, Maria-Rosa L. Cioni, Maria Ida Moretti +13
The "VISTA near-infrared YJKs survey of the Magellanic System" (VMC) is collecting deep Ks-band time-series photometry of pulsating stars hosted by the two Magellanic Clouds and th…
Magnetic structure of solar flare regions producing hard X-ray pulsations
I. V. Zimovets, R. Wang, Y. D. Liu +5
We present analysis of the magnetic field in seven solar flare regions accompanied by the pulsations of hard X-ray (HXR) emission. These flares were studied by Kuznetsov et al. (20…
The dynamical origin of multiple populations in intermediate-age clusters in the Magellanic Clouds
Jongsuk Hong, Richard de Grijs, Abbas Askar +7
Numerical simulations were carried out to study the origin of multiple stellar populations in the intermediate-age clusters NGC 411 and NGC 1806 in the Magellanic Clouds. We perfor…
Toward an internally consistent astronomical distance scale
Richard de Grijs, Frederic Courbin, Clara E. Martinez-Vazquez +3
Accurate astronomical distance determination is crucial for all fields in astrophysics, from Galactic to cosmological scales. Despite, or perhaps because of, significant efforts to…
Discovery of Extended Main Sequence Turn-offs in Four Young Massive Clusters in the Magellanic Clouds
Chengyuan Li, Richard de Grijs, Licai Deng +1
An increasing number of young massive clusters (YMCs) in the Magellanic Clouds have been found to exhibit bimodal or extended main sequences (MSs) in their color--magnitude diagram…
Improved method to determine the integrated properties of nuclear rings: NGC 1512
Chao Ma, Richard de Grijs, Luis C. Ho
The integrated properties of nuclear rings are correlated with their host galaxy's secular evolution and its dynamics, as well as with the formation and evolution of the ring's sta…
The VMC Survey - XXIV. Signatures of tidally stripped stellar populations from the inner Small Magellanic Cloud
Smitha Subramanian, Stefano Rubele, Ning-Chen Sun +12
We study the luminosity function of intermediate-age red-clump stars using deep, near-infrared photometric data covering 20 deg located throughout the central part of th…
Towards a unified view of inhomogeneous stellar winds in isolated supergiant stars and supergiant high mass X-ray binaries
Silvia Martínez-Núñez, Peter Kretschmar, Enrico Bozzo +13
Massive stars, at least 10 times more massive than the Sun, have two key properties that make them the main drivers of evolution of star clusters, galaxies, and the Universe…
